Conclusions • It seems to be possible to compare transparent and opaque colours • The pilot indicates that a computer screen could be used • NCS can be used and expanded to the chromatic area

Questions for the future • What kind of tool do designer/artists and producers need?

• How does thickness and shape affect the colour experience?

• What are the technical prerequisites for using a computer screen?
